SSRS 2016 Tablix Filter data type mismatch

Question

is this a bug in SSRS ? I have this 2 filters on my Tablix, #1 works fine but #2 produce type mismatch error, even It explicitly cast to INT in my code, and I put just 1 (without quotes in the box). Another thing that I don't have a choice to choose type in dropdown for second filter, it's faded unlike first one. I re-build report each time, those 2 are isolated fields coming from my Dataset. So problem probably comes how I can select Integer for type in second filter ?? Best. M

I heard that sometime SSRS has issues if you revert you changes, as XML code doesn't react properly.

Updated. IT works with those modifications:

Answer 1

Fixed this by modifying raw xml. Pros say this is common problem when xml changes don't retracted properly.
